Frequently asked questions
CosmoLex scores F on Supergood's API Report Card. No public REST API, developer portal, OAuth, or webhooks. The only programmatic surface is the official Zapier connector with nine triggers and seven create actions; there are no read, update, or delete operations. Storage, e-sign, and payments hookups are fixed point integrations.
Without a usable official API, teams fall back on manual exports, file drops, or one-off vendor integrations. The other option is an unofficial API layer like Supergood that automates the authenticated web app directly. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
CosmoLex is a cloud-based, all-in-one law practice management platform that bundles matter management, time tracking, billing and invoicing, document management, calendaring and tasks, client intake, e-signature, and, uniquely among LPM competitors, fully integrated three-way trust accounting and business accounting (no separate QuickBooks required, though a QuickBooks Online sync is offered).
Legal, specifically solo attorneys and small-to-mid-sized law firms (roughly 1–25 attorneys) in the U.S. and Canada that need trust/IOLTA accounting compliance baked into their practice management system. Attorneys and paralegals open matters, log time and expenses, generate and send invoices, accept LawPay/LexCharge online payments, and run trust deposits, disbursements, and three-way reconciliations directly inside the app.
Medium-high within the U.S./Canadian solo & small-firm LPM segment. CosmoLex is consistently named in the Clio / MyCase / PracticePanther / Smokeball / CARET Legal competitive set across G2, Capterra, and analyst comparisons, with hundreds of verified reviews on each.
CosmoLex sits on the entire operational and financial nervous system of a law firm: every matter file, client and contact record, conflict-check history, every time entry and expense, every invoice and payment, full IOLTA / trust ledger with three-way reconciliation, business general ledger, matter budgets, document index (with documents themselves often synced to OneDrive/Google Drive/Dropbox/Box/NetDocuments), calendars, tasks, notes, and intake forms.
Mid-mature. Launched in 2013 as a cloud-native, accounting-integrated LPM, a genuinely modern proposition at the time, CosmoLex is now 12+ years old and on its third corporate owner (independent → Tabs3 → ProfitSolv).
'CosmoLex does not publish a public REST API, developer portal, or programmatic authentication mechanism', no SCIM, no OAuth, no API keys, automated user lifecycle workflows are not supported. Webhooks and dedicated developer documentation are not generally available on apitracker.io's tracked surface, integrators are pushed to Zapier for any programmatic access.

Supergood's grades measure one thing: can a customer's engineering team get their own data out programmatically? Supergood checks six things (whether a real API exists, how access is gated, data coverage, auth quality, docs and developer experience, and stability) and rolls them into a letter grade. Supergood re-verifies grades, and they only move on evidence.
Yes, via a managed API layer. Supergood builds REST APIs and MCP servers for authenticated enterprise web apps, so AI agents and internal tools can read and write data programmatically. Site terms may apply to any integration approach, and how they apply is a determination each team makes for itself.
CosmoLex has partial MCP support. No official MCP server from CosmoLex or ProfitSolv exists, but an actively maintained community server on GitHub wraps the CosmoLex v1 integration API with 86 tools, OAuth setup, and install instructions for Claude Desktop. Adoption is minimal and roughly 20 features outside the v1 API are not covered.
Partially. MCP support for CosmoLex exists but is incomplete, so what MCP clients like Claude, Cursor, and Codex can reach depends on what the available server covers.
